Buy-Bust Operations: Entrapment vs Instigation in Illegal Drug Sales

The Supreme Court clarifies the distinction between entrapment and instigation in buy-bust operations, affirming a drug sale conviction.


The distinction between entrapment and instigation is one of the most frequently raised defenses in Philippine drug cases. Accused persons often claim that police officers induced them into committing a crime they had no intention of committing. In People v. Mendoza (G.R. No. 220759, July 24, 2017), the Supreme Court explained this distinction in the context of a buy-bust operation and affirmed a conviction for illegal sale of marijuana under Section 5, Article II of Republic Act No. 9165.

The Facts of the Case

In April 2006, a confidential informant reported to the Leyte Provincial Police Office that Armando Mendoza was selling illegal drugs in Carigara, Leyte. After surveillance confirmed the report, police planned a buy-bust operation. PO2 Elvin Ricote was designated as the poseur-buyer, with marked P100 bills prepared for the transaction.

On April 20, 2006, the informant introduced PO2 Ricote to Mendoza at a sari-sari store. Mendoza quoted P50 per teabag of marijuana, and PO2 Ricote agreed to buy four teabags. Mendoza handed over the drugs, received the marked money, and was arrested after the pre-arranged signal was given. A search yielded two additional teabags of marijuana from his pocket.

Mendoza was charged with both illegal sale (Section 5) and illegal possession (Section 11) of dangerous drugs. The trial court convicted him on both counts. On appeal, the Court of Appeals affirmed the conviction for illegal sale but acquitted him on the possession charge because the prosecution failed to present the confiscated items in court.

The Issue: Entrapment or Instigation?

Before the Supreme Court, Mendoza argued that his arrest was the product of instigation, not entrapment. He claimed that the confidential informant introduced the poseur-buyer to him and essentially instructed him to sell marijuana — conduct that, in his view, showed the police originated the criminal intent.

The Court rejected this argument. Citing People v. Dansico (G.R. No. 178060, February 23, 2011), the Court restated the classic distinction:

  • Instigation occurs when the accused is lured into committing a crime he had no intention to commit. The criminal intent originates from the inducer. This defense leads to acquittal.
  • Entrapment occurs when law enforcement merely facilitates the apprehension of a criminal who already has the intent to commit the offense. The criminal design originates in the mind of the accused. This does not bar prosecution and conviction.

Why the Court Found Entrapment

The Court found that the police had conducted prior surveillance confirming Mendoza's drug-selling activities before the buy-bust. The informant merely introduced the poseur-buyer; it was Mendoza who quoted the price, produced the marijuana, and completed the sale.

Significantly, the Court noted that "decoy solicitation" — where a police officer or informant asks to buy drugs from a suspected pusher — is not prohibited by law and does not invalidate a buy-bust operation. The sale of contraband is a habitually committed offense, and the solicitation simply furnishes evidence of the criminal's course of conduct.

Other Points Addressed

The Court also disposed of several procedural arguments:

  • Marked money not in the police blotter: Neither law nor jurisprudence requires buy-bust money to be entered in the police blotter. The money was presented and identified in court.
  • Chain of custody: The Court found no break in the chain. The seized items were inventoried at the barangay hall, marked in the presence of the accused and witnesses, delivered to the crime laboratory, and presented in court with intact markings.
  • Minor inconsistencies: Discrepancies in testimony about who marked the items or how many teabags were sold did not destroy credibility, as the poseur-buyer's testimony was consistent with documentary evidence.

The Ruling

The Supreme Court dismissed the appeal and affirmed the conviction for illegal sale of dangerous drugs. Mendoza was sentenced to life imprisonment and fined P1,000,000. The Court noted that while Section 5 of RA 9165 originally allowed the death penalty, Republic Act No. 9346 prohibits its imposition, leaving life imprisonment as the penalty.

Practical Takeaways

  • Entrapment is lawful; instigation is not. Police may set up a buy-bust to catch a suspected pusher, but they cannot plant the criminal intent in an innocent person.
  • Prior surveillance strengthens the prosecution's case. Evidence that the accused was already engaged in drug selling before the buy-bust shows the criminal intent existed independently of police action.
  • A decoy solicitation does not invalidate a buy-bust. Asking a suspected pusher to sell drugs is a legitimate technique, not instigation.
  • Chain of custody is critical. The prosecution must account for seized drugs from confiscation to court presentation. Gaps can lead to acquittal, as happened with the possession charge in this case.
  • Minor inconsistencies in police testimony do not automatically defeat a conviction. Courts weigh them against the totality of evidence, including documentary proof.
